Your analogy is better if the books or articles are written by the same users, like eg research papers and the editors (like Springer) dont allow the writers to even share their articles on the web.
Relevant info: the lawsuit of craigslist vs padmapper and 3taps: "3taps claimed that Craigslist was a public website, so anyone, including 3Taps always had authorization. The court disagreed with this..." (Wikipedia)
Agreed. But I still tought the top category app should drive so many installs that even users launching the app just once should generate more than that. Looks like the the business category is driving less installs than other more popular ones, like games or photo apps...
So, if I understand correctly you've the top biz category app and it's just generating ~100$ daily in ads? Seems a bit low actually :(
ps: would love some support for multiple data-sources per currency: for instance in Argentina we've official dollars but since they're impossible to get we also have sidemarket "blue" dollars...
My problem with this isn't that the advice is obvious, but rather obvious _only in hindsight_:
"The best startup ideas are the ones that seem like bad ideas but are good ideas.",
"the fast-growing market is going to be important but others dismiss it as unimportant"
these aren't obvious at all before they happen, not just for first-time startup people but everyone.
Agreed, we do have several vendors and do distribute the workload as much as possible. In our experience when a server goes down the whole data center has problems, so even if it's more inconvenient the best is to really have an assortment of vendors.
